High density polyethylene (HDPE) is the most frequently found non-degradable solid waste among the polyethylene which leads to innumerable environmental hazards. In the present study, HDPE degrading diverse fungal strains were isolated from the polyethylene garbage dumped sites of Thanjavur, Tamil Nadu, India and screened in aqueous culture under in vitro condition. The two fungal strains identified as A. flavus STR1 and Oidium Sp. STR2 by morphological characterization are capable of adhering to the surface of PE pieces, through enrichment technique. A thick network of fungal hyphae was observed on the surface of the plastic pieces under light microscope. Based on weight loss, viscosity and visible increase in growth and Spectrophotometric analysis, they were found to be efficient in HDPE degradation. The study further substantiated that the fungal isolates were considered for their ability to form hydrophobic proteins that can attach to the polymer and the ability of fungal isolates was proved to utilize virgin High Density polyethylene (HDPE) as the sole carbon source without any pre-treatment and pro-oxidant additives.
